-# 📈 Crypto Chart Patterns Detection
+# 📈 Crypto Chart Pattern Detector

+[![Test and Demo](https://github.com/tysoncung/crypto-chart-patterns/actions/workflows/test.yml/badge.svg)](https://github.com/tysoncung/crypto-chart-patterns/actions/workflows/test.yml)
 
-## 🎯 Overview
+Advanced technical analysis tool for detecting chart patterns in cryptocurrency markets.
 
-This project implements pattern recognition algorithms to identify common chart patterns in cryptocurrency price data, including:
-- **Inverse Head and Shoulders (IHS)** - Bullish reversal pattern

-## 📊 Usage
+## 📊 Quick Start
 
-### Basic Usage
+### Command Line Usage
 
-```python
-# Set the cryptocurrency pair
-stock = "ETHUSDT"
+```bash
+# Detect patterns for a specific symbol
+python pattern_detector.py --symbol ETHUSDT --interval 4h
 
-# Fetch data from Binance
-klines = get_data(stock)
-prices = binance_to_df(klines)
+# Run demo with all patterns
+python demo.py --symbol BTCUSDT --interval 1h
 
-# Detect patterns
-min_max = get_max_min(prices, smoothing=3, window_range=3)
-patterns = find_patterns(min_max)
+# Generate comprehensive report
+python generate_report.py
 
-# Visualize patterns
-plot_minmax_patterns(prices, min_max, patterns, stock, window=10, ema=30)
+# Run tests
+pytest test_patterns.py -v
 ```
 
-### Pattern Detection Parameters
+### Python API
 
-- **`smoothing`**: Moving average window for price smoothing (reduces noise)
-- **`window_range`**: Range for local extrema detection
-- **`ema_list`**: List of EMA periods to test [3, 10, 20, 30]
-- **`window_list`**: List of window sizes to test [3, 10, 20, 30]
-
-### Pattern Screening
+```python
+from pattern_detector import PatternDetector
+from enhanced_patterns import EnhancedPatternDetector
 
-Run a comprehensive pattern screen across multiple parameters:
+# Initialize detector
+detector = PatternDetector("BTCUSDT", "1h")
 
-```python
-ema_list = [3, 10, 20, 30]
-window_list = [3, 10, 20, 30]
-results = screener(resampled_prices, ema_list, window_list, plot=True, results=True)
-```
+# Run complete analysis
+results = detector.run_analysis()
 
-## 📈 Pattern Definitions
+# Or step by step:
+klines = detector.get_data(limit=500)
+prices = detector.binance_to_df(klines)
+max_min = detector.get_max_min(prices)
+patterns = detector.find_patterns(max_min)
 
-### Inverse Head and Shoulders (IHS)
-- **Formation**: Three troughs with the middle one being the lowest
-- **Condition**: `B > A > C; D > E > C`
-- **Signal**: Bullish reversal pattern
-- **Detection Logic**: `a<b and c<a and c<e and c<d and e<d`
+# Enhanced patterns
+enhanced = EnhancedPatternDetector()
+all_patterns = enhanced.detect_all_patterns(prices, max_min)
+```
 
-### Double Top (DT)
-- **Formation**: Two peaks at approximately the same level
-- **Condition**: `A < C < B; D > C > E`
-- **Signal**: Bearish reversal pattern
-- **Detection Logic**: `a<c and c<b and c<d and c>e`
+## 🧪 Testing
 
-## 📉 Forward Returns Analysis
+Run the comprehensive test suite:
 
-The tool calculates forward returns at different time intervals:
-- 1 period forward return
-- 12 periods forward return
-- 24 periods forward return
-- 36 periods forward return
+```bash
+# Run all tests
+pytest test_patterns.py -v
 
-This helps validate the predictive power of detected patterns.
+# Run with coverage
+pytest test_patterns.py --cov=pattern_detector --cov=enhanced_patterns
 
-## 🎨 Visualization
+# Run specific test
+pytest test_patterns.py::TestPatternDetector::test_triangle_pattern_detection
+```
 
-The tool provides two types of visualizations:
-1. **Price chart with all local extrema** - Shows detected peaks and troughs
-2. **Pattern overlay chart** - Highlights detected patterns on the price chart
+## 🚀 CI/CD
 
-## 🔧 Customization
+This project uses GitHub Actions for continuous integration:
 
-### Adding New Patterns
+- **Automated Testing**: Multiple Python versions (3.8-3.11)
+- **Coverage Reporting**: Integration with Codecov
+- **Daily Demos**: Scheduled pattern detection runs
+- **Artifact Generation**: Analysis reports and visualizations
 
-To add a new pattern, modify the `find_patterns()` function:
+## 📈 Pattern Types
 
-```python
-def find_patterns(max_min):  
-    patterns = defaultdict(list)
-
-    for i in range(5, len(max_min)):  
-        window = max_min.iloc[i-5:i]
-        a, b, c, d, e = window.iloc[0:5]
-
-        # Add your pattern logic here
-        if your_pattern_condition:
-            patterns['YOUR_PATTERN'].append((window.index[0], window.index[-1]))
-
-    return patterns
-```
+### Basic Patterns
+1. **Inverse Head and Shoulders (IHS)** - Bullish reversal
+2. **Head and Shoulders (HS)** - Bearish reversal
+3. **Double Top (DT)** - Bearish reversal
+4. **Double Bottom (DB)** - Bullish reversal
 
-### Changing Data Source
+### Triangle Patterns
+5. **Ascending Triangle** - Bullish continuation (flat top, rising bottom)
+6. **Descending Triangle** - Bearish continuation (falling top, flat bottom)
+7. **Symmetrical Triangle** - Neutral (converging lines)
 
-Currently uses Binance API. To use another exchange:
+### Wedge Patterns
+8. **Rising Wedge** - Bearish reversal (converging upward)
+9. **Falling Wedge** - Bullish reversal (converging downward)
 
-```python
-def get_data(stock):
-    # Modify URL for your exchange's API
-    url = f"YOUR_EXCHANGE_API_URL"
-    r = requests.get(url)
-    # Parse according to your exchange's format
-    return data
-```
+### Flag Patterns
+10. **Bull Flag** - Bullish continuation after strong upward move
+11. **Bear Flag** - Bearish continuation after strong downward move
 
-## 📊 Performance Metrics
+### Channel Patterns
+12. **Ascending Channel** - Upward trending parallel lines
+13. **Descending Channel** - Downward trending parallel lines
+14. **Horizontal Channel** - Sideways trading range
 
-The screener provides average results grouped by:
-- Window parameter
-- EMA parameter
-- Stock symbol
-- Individual pattern performance
+### Special Patterns
+15. **Cup and Handle** - Bullish continuation (U-shape with handle)
